U.S. authorities have arrested a third New York man in connection with an alleged plot to detonate pressure cooker bombs in New York City for the self-proclaimed Islamic State, or ISIS.

The latest arrest involved a 21-year-old Staten Island man named Fareed Mumuni who allegedly tried to kill a law enforcement official who came to his house earlier today. The criminal complaint alleged that he repeatedly attempted "to stab an FBI Special Agent with a large kitchen knife."

More than two years after the self-proclaimed Islamic State burst on the scene, it is still difficult to quantify just how big the threat is in this country. Counterterrorism officials say nearly 200 Americans have traveled to Syria and Iraq, are thinking about doing so or have returned to the U.S. after spending time there.

NPR has learned that number of returnees in this country is nearly three dozen — but their cases remain sealed.

Last week in the United Arab Emirates, group of Muslim scholars held what they called a "haqqathon" – a hackathon meant to create new ways for Islamic scholars to connect with young Muslims and, by doing so, defuse violent extremists like the self-proclaimed Islamic State.

And al-Qaida is at the center of a pretty stunning announcement from the White House this morning. President Obama said two hostages of al-Qaida, including an American, were killed in a U.S. counterterrorism operation.
